Answer 1

DOT tanker codes, established by the U.S. Department of Transportation, are identification codes assigned to various types of tank vehicles that transport hazardous materials. Each code consists of a letter and a number, where the letter indicates the type of tank (e.g., "A" for non-pressure cargo tanks, "B" for pressure cargo tanks) and the number signifies specific construction or design features. These codes help ensure the safe handling and transportation of hazardous materials by providing essential information about the tank's capabilities and limitations.
